The jewellery trick Princess Diana did that impressed everyone

In 1985, pictures of Princess Diana and Prince Charles dancing together in Melbourne, during their tour of Australia, made headlines.

Of course, people were happy to see them dancing, but more importantly, they were further proof of Diana's style icon status.

For the evening, the Princess wore a green one-shoulder gown, which she paired with diamond and emerald earrings and what appeared to be a matching headband, except it wasn't.

Purely by accident, she fitted a choker necklace over her head, and loved the effect so much, she kept it there.

In her book, The Royals, journalist and royal biographer Kitty Kelley wrote, ‘Diana took the necklace and put it over her head rather than wait to have it clasped around her neck. She couldn’t get it over the bridge of her nose. "My honker’s too big," she said. Vic [Victor Chapman, a Canadian diplomat] roared. "Leave it there," he said. "It’s young and fun, like you."'

Diana of course kept it there, creating a totally new trend. The emerald choker itself was originally gifted to Queen Mary by the Ladies of India in 1911, which was then given to Diana on a lifetime loan by Queen Elizabeth II shortly after her wedding to Charles.

She moved to the UK permanently and has never looked back (though she does go back regularly to stock up on cheese and wine).

Although she's always loved fashion - she used to create scrapbooks of her favourite trends and looks, including Sienna Miller and Kate Moss' boho phase - her first job was at, sourcing the best deals for everything from restaurants to designer sales.

However she quit after two years to follow her true passion, fashion journalism, and after many years of internships and freelance stints at magazines including Red, Cosmopolitan, Stylist and Good Housekeeping, landed her dream job as the Digital Fashion Editor at Marie Claire UK.

Her favourite part of the job is discovering new brands and meeting designers, and travelling the world to attend events and fashion shows. Seeing her first Chanel runway IRL at Paris Fashion Week was a true pinch-me moment.
